Within the administration area of the tool, there is access to help that serves to guide users on the use of this. But in the setup screens there is no help that can guide users through this process.

Were made to follow the following steps to implement this improvement:

1. Search are located in the folder where the files related to the Joomla installation (installation folder), with the help of Firebug (Mozilla Firefox extension) it was possible to identify which was the span of the buttons corresponding to the region of installation.
2. Insert a div corresponding to the button you wanted to add help at the facility. Each step of the installation corresponds to a different php, so this was added span in each of these files.
3. In templates.css file, located in the installation folder \ template \ css \ template.css was done formatting the appearance of the div.
4. I inserted a link pointing to the page containing the doc.joomla step by step to installing version 2.5.
